Drivers and approach to Sustainability
Environment / NR Policy
• NR & Mace sustainability Policy
• New builds – BREEAM ‘Excellent,’ refurb
‘Very Good’ – GATEWAY PROJECT
• Pollution and climate change
Legislation
Economic
• Building Regulations
• Payback / IRR / NPV
• Whole Life costs
Design/Engineering
• EU Buildings Directives
• Drive for efficiency
• CRC / RHI
• Rising cost of fuel
• Cost/benefit
• Planning Policies
Social responsibility
• Community engagement
• Design with future in mind
• Carbon footprint reduction
• Social inclusion

Challenges & Constraints of Refurbishment
• Limited insulation with existing façade
retained
• Accessibility for passengers increases open
areas to outside – issue for thermal comfort
• 28 new escalators, 31 new lifts – increase of
energy demand – from 9GWhr to 14
GWhr/Year
• Open track area below concourse with
Overhead Lines – limited areas to insulate
• Limited space for renewables ideas (i.e.
Biomass space and sub-surface regs) and
many third party interfaces

Low / Zero Carbon Technology Study
• Consultant Atkins carry out a study to establish viability
of low carbon technology (Sep’t 09’)

Challenges for CHP
• Complicated contract for ESCO – Works and
maintenance elements
• Unfamiliar contract and risk to Network Rail
• Integrate design & operation into a complex Gateway
project
• High electrical load / low heat demand
• Asset Protection for station operations
• Long terms contracts – 25 years typical
• Asset owners and RAMS acceptance is critical
• Third party access rights and protocol required
Possible Routes – use of sub platform tunnel Networks
Benefits for CHP at New Street
• Significant reduction in Carbon emissions >3,000Ton/yr
& supports BCC carbon reduction targets
• Provide model case for role out to other managed
stations
• Reduction in energy bills
• Use of strategic tunnel network avoiding disruptive
infrastructure works around the city
• Potential for significant expansion of the system with
heat provision to adjacent buildings
• Provision for South side to be ‘CHP ready’
• CRC benefits to Network Rail
